P460NH steel is a normalized weldable fine grain steel. Executive standard: EN10028-3, steel number: 1.8935. P460NH steel is alloy special steel for S690QL steel mechanical properties pressure equipment. P460NH steel has good plasticity, toughness, cold bending performance and welding performance. P460NH steel plates are usually delivered in normalized condition. According to the negotiation between the supplier and the buyer, normalizing rolling can be used instead of normalizing. In this case, the sample shall be subject to simulated normalizing according to the agreed test frequency to verify that the performance meets the requirements.

Steel plates for high-rise buildings have the properties of easy welding, earthquake resistance, and low-temperature impact resistance, and are mainly used in large-scale projects such as high-rise buildings, super-tall buildings, large-span stadiums, airports, exhibition centers, and steel structure workshops. Compared with ordinary Q235B / Q345B steel plates, these plates S690QL steel mechanical properties for high-rise buildings have upper limits on yield strength and improved tensile strength, and have requirements for carbon equivalent and yield ratio indexes.

The effect of alloy elements of S690QL steel mechanical properties, Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.

The requirements for toughness impact energy of S690QL steel mechanical properties, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.
